Difference between interface and conversion

could you give me the difference between interface and conversion

hi
<b>Conversion,</b> converting legacy system data into SAP data. Meaning that it is mainly a one shot deal, for example bringing your customer master to SAP from the legacy system, converting the fields used in legacy to the fields and values used in SAP.
<b>Interface,</b> a program or group of programs that handle the passing of data from one system to another. These programs work together to export the data from one system and import into a target system, maybe these programs run once a day, maybe twice, may every hour throughout the day. It is a good way to keep the data in two or more systems in sync with each other.
Interface programs are also data extract program. Data is extracted from SAP into a flat file and transferred to other external systems like UNIX, mainframe.
In data extracts, the file layout is designed and this layout should be in synch with other external systems.

  • Difference between Interface node and normal node?

    What is the main difference between  Interface node and normal node?
    Cheers
    Aisurya.

    Hi surya,
    Interface node or methods comes into picture whenever you want to use one component as used component. I mean to say
    Component usages. If you select node as interface node, it will available in another component so you can use that node or methods.
    Normal node means in that component only. Simply we can say for component usages we go for interface nodes.

  • Difference between interface pool and class pool

    Hi,
    Can any body tell me the difference between Interface pool and Class pool.
    thank you in advance.
    regards

    Hi,
    Class and Interface Pools
    This section discusses the structure and special features of class and interface pools for global classes.
    Global Classes and Interfaces
    Classes and interfaces are object types. You can define them either globally in the Repository or locally in an ABAP program. If you define classes and interfaces globally, special ABAP programs called class pools or interface pools of type K or J serve as containers for the respective classes and interfaces. Each class or interface pool contains the definition of a single class or interface. The programs are automatically generated by the Class Builder when you create a class or interface.
    A class pool is comparable to a module pool or function group. It contains both declarative and executable ABAP statements, but cannot be started on its own. The runtime system can create runtime instances (objects) through a request using the CREATE OBJECT statement. These objects execute the statements of the class pool.
    Interface pools do not contain any executable statements. Instead, they are used as containers for interface definitions. When you implement an interface in a class, the interface definition is implicitly included in the class definition.
    Structure of a Class Pool
    Class pools are structured as follows:
    Class pools contain a definition part for type declarations, and the declaration and implementation parts of the class.
    Differences From Other ABAP Programs
    Class pools are different from other ABAP programs for the following reasons:
    ·        ABAP programs such as executable programs, module pools, or function modules, usually have a declaration part in which the global data for the program is defined. This data is visible in all of the processing blocks in the program. Class pools, on the other hand, have a definition part in which you can define data and object types, but no data objects or field symbols. The types that you define in a class pool are only visible in the implementation part of the global class.
    ·        The only processing blocks that you can use are the declaration part and implementation part of the global class. The implementation part may only implement the methods declared in the global class. You cannot use any of the other ABAP processing blocks (dialog modules, event blocks, subroutines, function modules).
    ·        The processing blocks of class pools are not controlled by the ABAP runtime environment. No events occur, and you cannot call any dialog modules or procedures. Class pools serve exclusively for class programming. You can only access the data and functions of a class using its interface.
    ·        Since events and dialog modules are not permitted in classes, you cannot process screens in classes. You cannot program lists and selection screens in classes, since they cannot react to the appropriate events. It is intended to make screens available in classes. Instead of dialog modules, it will be possible to call methods of the class from the screen flow logic.
    Local Classes in Class Pools
    The classes and interfaces that you define in the definition part of a class pool are not visible externally. Within the class pool, they have a similar function to local classes and interfaces in other ABAP programs. Local classes can only be instantiated in the methods of the global class. Since subroutines are not allowed in class pools, local classes are the only possible modularization unit in global classes. Local classes have roughly the same function for global classes as subroutines in function groups, but with the significant exception that they are not visible externally

  • Weird Differences Between 32 and 64 bit Conversions

    Windows Users:
    Ever convert exactly the same raw file using exactly the same parameters into 16 bits/channel images with Photoshop CS6 32 bit and 64 bit, overlay them, set the top layer to "Differences", then add a couple of extreme curves adjustment layers over the top?
    Amazingly, there's a difference between the two conversions.
    Even more amazingly, while there's a slight correllation to the image content, there are patterns in the differences that don't really match much of anything in the image, yet they differ from raw file to raw file.
    Try it some time.  If you can't reproduce it, I'll be happy to share my raw file.
    Here are two small images, the converted raw file, and the enhanced differences between a 32 and 64 bit conversion of that same raw file.
    Enhanced/blurred differences betwen the 32 and 64 bit conversions.
    Artificial intelligence trying to express itself?  Cosmic rays?  Kirlean messages from Beyond? 
    I happened to be using the 32 bit Photoshop today to access some plug-ins I only can get in 32 bits, converted the same image in both, and just wondered whether there might be differences.  You never know what you'll find until you look!
    Oh, and sorry Mac folks - I know you only have a 64 bit converter to play with.
    I'm reminded of the old adage:  A man with one watch knows what time it is.  A man with two watches is never sure.
    -Noel

    Thanks for your response, Eric.
    I understand what you're saying, but a several bit difference in a 15 bit result is actually quite a lot to be attributed to math inaccuracy due to floating point operations.  Even single precision 32 bit floating point operations should give you 24 bits of precision.  A few bits at the end shouldn't add up to a visible difference, unless decisions are being made in the code based on results (e.g., if noise > threshold, do something).
    Perhaps you don't use the Strict Floating Point Model, because if you did that should give you consistent results.
    I've been through the decision of which floating point model to use in my own software, initially thinking that the Fast model would be better for speed (obviously), but as it turns out the repeatability of results with the Strict model is well worth the tiny bit of extra time it takes for the results to be predictable.  You might want to reconsider using Strict, as I have, especially if these are not just round-off errors but decisions being made in the code based on floating point results.  Looking around on the web, I see more folks than just I have made that specific choice.
    Food for thought.

  • Difference between interface view and interface controller

    Hi,
    What is the difference between interface controller and interface view?
    When we will use interface controller and when we will use interface view?
    How do we create an interface view?
    How do we attach this interface view to a view in another component
    Regards
    MQ

    Hi
    Interface View Controllers
    A) Implement event handlers which are called when ..
           -starting (start-up plugs) Web Dypro applications
           -a component is reached via navigation (inbound plugs)
    B) Allow fireing outbound plugs (navigation)
    C) Allow firing exit plug
    D) Have no own context, public methods or events
    Interface Controller of a Component
    The interface controller of a Web Dynpro component contains all context nodes, events and methods of the component controller to which you assigned the Interface addition in the Controller Editor. These parts can be displayed in the interface controller view, although you cannot edit them here.
    Interface Controller of a Component Interface
    A Web Dynpro component interface can be created independently and defined so that it can be implemented later in any components (see working with Web Dynpro Component Interfaces in the Programming Manual of this documentation). That is why in this case you can define the context nodes, methods and events you require in the interface controller view. The relevant implementation then takes place in the component controller of the implementing component.
    Check this links and work on it.

  • What is the Difference Between Adapter and Proxy

    Hi Master,
    I want to know the Difference Between Adapters and Proxies.
    And when we are using proxies and Adapters....
    Regards,
    SReddy

    Adapters are part of the Adapter Framework. Adapters provide the technical connectivity to enable the integration of SAP and non-SAP applications through XI’s Integration Engine.Again, Adapters are used for connectivity from and to external systems with XI that cannot communicate via proxies.Adapters are only required in SAP systems older than 6.20 and external systems.
    Systems based on 6.20or higher can communicate directly with proxies.
    The literal definition of a proxy is an object / process authorized to act for another; an agent or a substitute. In simpler terms, proxies in the XI context are objects used to encapsulate the creation (from a sender system) or parsing of XML (at a receiver system) as well as the communication with the relevant runtime components required to send or receive those messages.
    Proxies are generated from Message Interface in IR.
    The Proxy Runtime controls these objects / processes, and can itself be controlled by the applications it communicates with. The Proxy Runtime currently has the following components available: 1. ABAP Proxy Runtime – Communication using XI or Web Services a. Web Service Runtime 2. Java Proxy Runtime – Communication using XI (J2EE) The objects that the Proxy Runtime then controls are created via Proxy Generation, for both ABAP and Java. In the following sections a ‘client’ proxy is used by an application to send messages outside of the system it resides in (normally to the IS in this context). Conversely, a ‘server’ proxy is used by an application to receive messages from sources outside itself (again, normally the IS in this context).

  • Difference between idoc and rfc

    what is the difference between idoc and rfc? when and where it is used? when there is idoc, why rfc vice versa?

    IDoc (for intermediate document) is a standard data structure for electronic data interchange (EDI) between application programs written for the popular SAP business system or between an SAP application and an external program. IDocs serve as the vehicle for data transfer in SAP's Application Link Enabling (ALE) system. 
    IDocs are used for asynchronous transactions:  Each IDoc generated exists as a self-contained text file that can then be transmitted to the requesting workstation without connecting to the central database. 
    Another SAP mechanism, the Business Application Programming Interface (BAPI) is used for synchronous transactions. 
    A large enterprise's networked computing environment is likely to connect many geographically distributed computers to the main database. These computers are likely to use different hardware and/or operating system platforms. An IDoc encapsulates data so that it can be exchanged between different systems without conversion from one format to another. 
    IDoc types define different categories of data, such as purchase orders or invoices, which may then be broken down into more specific categories called message types. Greater specificity means that an IDoc type is capable of storing only the data required for a particular transaction, which increases efficiency and decreases resource demands. 
    An IDoc can be generated at any point in a transaction process. For example, during a shipping transaction process, an IDoc may be generated that includes the data fields required to print a shipping manifest. After a user performs an SAP transaction, one or more IDocs are generated in the sending database and passed to the ALE communication layer. The communication
    layer performs a Remote Function Call (RFC), using the port definition and RFC destination specified by the customer model. 
    The IDoc is transmitted to the receiver, which may be an R/3, R/2, or some external system
    RFC
    Remote Function Calls (RFC) and data exchange through IDoc message documents. RFC makes direct and synchronous calls of a program in the remote system. If the caller is an external program it will call an RFC-enabled function in R/3 and if the calling program is the R/3 system it will call an RFC-function in another R/3-system or it will call a non-R/3 program through a gateway-proxy (usually rfcexec.exe). BAPIs are a subset of the RFC-enabled function modules, especially designed as Application Programming Interface (API) to the SAP business object, or in other words: are function modules officially released by SAP to be called from external programs.

  • Differences between LSMW and BDC

    Hi All
    Please can you give me the few points about the differences between LSMW and BDC?
    Awaiting for your Responce
    Praveen

    Hai Check with the following document
    GOOD
    THERE IS THREE TYPE OF METHOD IN BDC
    BDC SESSION
    CALL TRANSACTION
    CALL DIALOG
    What is BDC or batch input
    The Batch Input is a SAP technic that allows automating the input in transactions. It lies on a BDC (Batch Data Commands) scenario.
    BDC functions:
    · BDC_OPEN_GROUP : Opens a session group
    · BDC_CLOSE_GROUP : Closes a session
    · BDC_INSERT : Insert a BDC scenario in the session
    · The ABAP statement "CALL TRANSACTION" is also called to run directly a transaction from its BDC table.
    It runs the program RSBDCSUB in order to launch automatically the session. The session management is done through the transaction code SM35.
    The object itself is maintanable through the transaction SE24.
    BDC methods:
    Method
    Description
    Parameters
    OPEN_SESSION
    Opens a session
    SUBRC (Return Code – 0 OK)
    SESSIONNAME (Session to be created)
    CLOSE_SESSION
    Closes a session
    None
    RESET_BDCDATA
    Resets the BDC Internal Table...
    None. Normally, for internal purpose…
    BDC_DYNPRO
    Handles a new screen
    PROGNAME (Name of the program)
    DYNPRONR (Screen Number)
    BDC_FIELD
    Puts a value on the screen
    FIELDNAME (Name of the field)
    FIELDVALUE (Value to be passed)
    CONSTRUCTOR
    Constructor - Initializes NO_DATA
    NODATA (No data character). The constructor is called automatically when the object is created.
    RUN_SESSION
    Launches a session with RSBDCBTC
    None
    CALL_TRANSACTION
    Calls a transaction with the current BDC Data
    MODE (Display Mode)
    UPDATE (Update Mode)
    TCODE (Transaction to be called)
    BDC_INSERT
    Inserts the BDC scenario in the session
    TCODE (Transaction to be called)
    BDC techniques used in programs:
    1) Building a BDC table and calling a transaction,
    2) Building a session and a set of BDC scenarios and keeping the session available in SM35,
    3) Building a session and lauching the transaction right after closing the session.
    BDC using Call Transaction
    BDC using Call transaction involves calling an SAP transaction in back ground from within the ABAP
    program. The process involves building an Internal BDC table containing the screen information needed to
    execute the required transaction and then passing this to the Call transaction command (See code example).
    The full procedure for creating a BDC program is as follows:
    What is the difference between batch input and call transaction in BDC?
    Session method.
    1) synchronous processing.
    2) can tranfer large amount of data.
    3) processing is slower.
    4) error log is created
    5) data is not updated until session is processed.
    Call transaction.
    1) asynchronous processing
    2) can transfer small amount of data
    3) processing is faster.
    4) errors need to be handled explicitly
    5) data is updated automatically
    BATINPUT/DIRECT INPUT
    A: Batch-inputs can not be used to fill the "delivery due list" screen because it is not a dynpro. This is a standard SAP report. A SAP report (check with "System -> Status") may be called using SUBMIT sentence with the appropriate options . It is preferred to call a report than create a Batch-input program.

    The LSM Workbench is an SAP R/3 based tool that supports the one-time or periodic transfer of data from non-SAP systems ("legacy systems") to SAP systems.
    The LSM Workbench helps you to organize your data migration project and guides you through the process by using a clear sequence of steps.
    The most common conversion rules are predefined. Reusable conversion rules assure consistent data conversion for different data objects.
    LSMW vs DX Workbench
    The LSM Workbench covers the following steps:
    Read the legacy data from one or several files (e.g. spreadsheet tables, sequential files).
    Convert the data from source format to target format.
    Import the data using standard interfaces (Batch Input, Direct Input, BAPI, IDoc).
    Experiences made in successful implementation projects have shown that using the LSM Workbench significantly contributes to accelerating data migration.
    SAP provides this tool along with documentation to customers and partners free of charge.
    Users of the LSM Workbench receive the usual support via SAP Net - R/3 Frontend (component BC-SRV-DX-LSM).
    Releases:
    Version 1.7.2 of the LSM Workbench ("LSMW 1.7.2") available
    Attention : LSMW 1.7.2 requires an SAP R/3 system with SAP R/3 4.0 or SAP R/3 4.5.
    Version 1.8.0 of the LSM Workbench (1.21mb) ("LSMW 1.8.0") available
    Attention : LSMW 1.8.0 requires an SAP R/3 system with SAP R/3 4.6.
    Version 3.0 of the LSM Workbench (1.89mb) ("LSMW 3.0") available for Web Application Server 6.10
    Attention : LSMW 3.0 requires a SAP WAS 6.10. Functionality of version 1.7.2 and 3.0 are identical !
    Version 4.0 of the LSM Workbench ("LSMW 4.0") integrated in Web Application Server 6.20
    Attention : LSMW 4.0 is an integrated part of SAP WAS 6.20.

    Dear Expert,
    I need to know what is the difference between SFP+ and X2! and can I use SFP+ card and module instead of X2?
    Thanks,
    Mohammad Saeed

    Hi,
    They are both used for 10Gig interfaces.  The difference is the connector type.
    SFP+ is LC and X2 is SC.
    You can not put an SFP+ into an X2 slot or X2 optic into a SFP+.

  • What is the difference between #variable_name and :variable_name?

    Hi!
    What is the difference between #variable_name and :variable_name?
    I have found that if we use alphanumeric variable then :variable_name return value in quotes but #variable_name without quotes.
    Why it does not work in the same way for variable default values when variable is used in filter? (It works in mapping)
    I use variable in filter like T.OUT_DATE>convert(datetime,:LAST_UPDATE_DATE,121)
    When I use my variable in package and do refresh it works fine. But when I try to execute the same interface with variable default value I get error. Seems that variable name has been not changed to the value. It does not work with default value in quotes neither without quotes.
    Any ideas how to solve that?
    Thank you in advance!
    Edited by: user13278245 on Sep 15, 2010 4:34 AM

    Question is how to make it work with default value, when I execute interface standalone, not in package? And why it works in mapping but not in filter?
    + I have found that it works if source is Oracle. It doesn't work only for MS SQL source.

    what is the difference  between ws_upload and gui_upload
    what is the difference  between ws_download and gui_down load
    pls tell  briefly

    Hi Kuamr,
    UPLOAD and DOWNLOAD, the function modules used until now are not part of the standard set of ABAP commands. They are used to display the file interface on the presentation server. UPLOAD and DOWNLOAD are not compatible with USs and have been replaced by GUI_UPLOAD and GUI_DOWNLOAD.
    The new function modules, GUI_UPLOAD and GUI_DOWNLOAD, have an interface that also allows you to write Unicode format to the local hard drive. For a description of these interfaces, refer to the documentation for each function module, available under SAP Easy Access " Development " Function Builder " Goto " Documentation.
    Instead of using the function modules, you can use the static methods GUI_UPLOAD and GUI_DOWNLOAD of the global class CL_GUI_FRONTEND_SERVICES.
    Hope this resolves your query.
    Reward all the helpful answers.
